Printed circuit board structure for solid state drive

A printed circuit board (PCB) structure for a solid state drive is provided. In an embodiment, a solid state drive includes top and bottom layers, a plurality of intermediate layers, and a ground cage. Each of the top layer and the bottom layer includes a plurality of components for operating the solid state drive. A plurality of intermediate layers enable electrical signals to pass between the components on the top layer and the bottom layer, one of the plurality of intermediate layers including a power plane having a high voltage relative to each of the other planes. The ground cage shields signal traces located in the same layer as the power plane and planes in adjacent layers from noise generated by the power plane. 本发明提供一种用于固态驱动器的印刷电路板(PCB)结构。在实施例中，固态驱动器包括顶层和底层、多个中间层和接地笼。顶层和底层中的每一层包括用于操作固态驱动器的多个组件。多个中间层使得电信号能够在顶层和底层上的组件之间传递，多个中间层中的一层包括相对于其他平面中的每一个具有高电压的电源平面。接地笼屏蔽与电源平面位于相同层的信号迹线以及相邻层中的平面，以免受电源平面所产生的噪声的影响。
